To all whom it may concern:

Be it V4known that 1,.,NATHAN C. BRODER- soN, a citizen of the UnitedStates, residing at Sycamore, county of Dekalb', and State of Illinois, `have invented certain new and useful Improvements in Check-Row Corn- Planters, of which vthe following'is a specification.` Y f more particularly to that class knownV as check-row corn-planters. f

i The object of my invention is vto provide a check-row attachment for planters ofthe character mentioned, which 4'will dispense entirely with the use of wire or other like contrivances for checking the corn ein lrows when planting, the Vlatter although very awkward and not `easily operated being nevertheless a necessity in corn-planters in general use at the present time; and to `accomplish the same result just as efficiently by providing a simple and easily operated' check-row mechanism which may be made to form an attachment for, orbe manufacthe corn-plant-r tured simultaneously with, ers in general use at present.

A further obj ect of myl invention is to provide a check-row attachment forplanters of the vcharactermentioned, which will readily accommodate itself to the nature of the' accurately ac- A further object of vmy invention is to provide a device of the class mentioned e uippedv with means 4for raising the corn p anting mechanism and the check-row device simultaneously.

A further obj ect of my invention is to provide a device as mentioned which will be strong, durable, and as stated, of simple construction, hence oflow cost to manufacture.

Other objects will appear hereinafter.

With these objects 1n view my invention consists generally ina frame mounted upon draft wheels, in'combination with a runner or seed planter fr-ame hingedly connected thereto, seed dropping-mechanism arranged on the lastsaid frame, a4 rotary shaft mounted thereon for actuating said mechanism, second shaft rotatably mounted on said frame and operably connected with the first said shaft, a'pair of arms pivotally `mounted on the last said shaft, a marker shaft rotatably Y v bination with means on the main frame for My invention relates to corn-planters, and

tion, and in which,

Figure 1 is atop plan view of a corn-planter providedv with the preferred form of my check-row mechanism, Fig. 2 is a vertical longitudinal section of the same taken on the line x-r of Fig. 1, and Fig. 3 is a vertical transverse section taken substantially on the line y-fy of Fig. 1.

Referring now to the drawings, 1 indicates the ordinary frame of a corn-planter, and 2 the draft-wheel axle to which it is suitably secured, l3 indicating the ordinary draftwheelsv rotatably mounted upon said axle. Said framing 1 iscomposed as is usual, of the rearwardstationary frame 4 and the forward vertically adjustable runner frame 5, the latter frames being hinged as at 6 and 6 to the forward endl portions of hinge bars or members 7, the rearward end portions of said hinge members being hinged as at 8 and 8 to the stationary frame 4. So as to facilitate vertical adjustment of the runner frame 5 as stated, the frame ll is provided with an obliquely disposed member 9, to which is secured a segmentalrack 9 and to which is fulcrumed'the bell crank hand lever 10, said lever being provided with an ordinary pawl which is adapted` to engage the notches in said segmental rack so as to hold the runner frame in adjusted position, and the forward end 11 of said lever being suitably secured as by a chain to the rearward end portion of the draft-tongue'lZ, said rearward end portion of said tongue being suitably secured as byiron bands 13 to;the runner*frame 5; By this arrangement it is obvious that the runner frame may be easily and readily adjusted by the operator.

Suitably secured as by screws 1 4 yto the tongue 12 is a shaft supporting bracket niember 15. Mounted or ournaled in said bracket meniber 15 is a horizontally disposed rockshaft 16. Rotatably mounted or jo'urnaled substantially centrally upon said rock-shaft and locked. together upon the same, are sprocket wheels 17 and 18. Suitably secured to either end of said rock-shaft 16 is a iioating shaft supporting member o1' arm 19. Rotatably mounted or journaled in said members 19 and positioned preferably directly above the seed-boxes ofthe planter, is a horizontally ,disposed shaft 20, iixed to either end ef which is a spade marker-wheel 21, each of said wheels being preferably composed, as shc'iwn' inthe accompanying drawings, of eight spade marking armsl 22, alternate arms of the same being provided at their outer ends with spades23 of a greater vf'idth than spades 24 secured to the ends of the arms 25 intermediate of said arms 22 as clearly shown inthe accompanying drawings and for a purpose hereinafter set forth. Suitably iixed as y a key to said spade marker-shaft 20 in aline/ment with the sprocket wheel 17, is a o'jcketwheel 26. Connecting said sprocket wheels 26 and 17 is a sprocket chain 27. Journaled in brackets 28 said brackets being vsuitably secured as by bolts or rivets l2Q to the runner frame 5, is ahorizontally disposed shaft 30. Fixed to said shaft in alincment withgsaid sprocket wheel 18 is a sprocket wheel 31. `Connecting said sprocket wheels 18 and 31 is a sprocket chain 32. Secured to the side of said sprocket wheel 31 and projecting radially therefrom, is a tappet 33. Seaidtappet 33 is provided with a roller 34 as clearly shown in Fig. 3 of the accompanying drawings. Said roller 34 of the tappet 33 is adapted when the gear-wheel 31 is rotated to rock or trip a trigger 35 fixed to a rock-shaft 36, said shaft being adapted when so operated toactuate the seed-dropping mechanism of the tseed-bones 37, `said boxes being of any ordinary or preferred form.

, The sprocket wheels 31 and 17 are preferably made half as large as the sprocket wheels 18, ,and 26, that is the former are provided with halt asmany teeth as the latter, and the spade marker-arms made of such a length that the distance betweentwo adjacent spade edgesis preferably 21 inches. With this arrangement it is obvious that the sprocket wheel 31 will revolve` four times while the spade marker-wheels revolve but once, and since lthe spades are 21 vinches apart and there areeight ofsaid spade arms, seeds will be dropped every 42 inches, which is the usual distance between rows ofcorn. It is to be understood -however that said sprocket Wheels may be proportioned differently than mentioned, and that said spade marker-arms made of a shorter or longer length than mentioned vso as to alter the distance between rows of seeds when planting as desired, with ou't departing from the spirit of my invention.

To facilitate elevating the spade marker wheels ont of contact with the ground when transporting the planter from field to field, or when turning at the ends of rows, I provide a bracket member 38,v the same being posi tioned directly under the spade marker-shaft 20 and suitably secured preferably by screws as shown in the drawings to the upper surface of the tongue 12. With this arrangement when the runners or furrowcrs which are secured to the runner frame 5 of the inachine, are raised, the same being necessary when transporting the machine or when turning, by the hand-leverlO, the bracket member 38 will obviously be raised sinnlitaneously with said frame, and which inturn will raise the spademarker-shaft and wheels from contact with the ground, thus obviating the necessity of any extra levers for perform` ing this function, the one ordinary runner frame vertically adjusting lever doing the work that otherwise would employ the use of two levers to perform.

In operating a machine provided with my attachment, that is, in planting corn, the machine is drawn over the field` as usual. The spades 23 and 24 of the spade markerwheels 21 being supported in floating supporting members will rest or obviously step along the ground leaving alternating long and short marks on the ground passed over. In returning that is, in drawing the machine in the opposite direction after having finished planting a row of seeds, the operator may readily check the rows of seed by steering the machine when driving so that the wide s )ade will register with the long marks, an' thc narrow spades with the short marks prcviously made on the ground when driving in. the opposite direction, thus facilitating easily andv accurately checking of the rows of seeds planted. A
